Hundreds of science center visitors learned about deoxyribonucleic acid(DNA) by making Inheritance Bracelets based on several one-gene traits, applying temporary DNA tattoos, and creating beaded key chains in the form of DNA sequences. DNA Day celebrates the discovery of the DNA double helix and the completion of the Human Genome Project in 2003.

X PRIZE also marked DNA Day by unveiling the world’s largest LEGO DNA sculpture, the “Building Bricks of Life” created by famed brick artist Nathan Sawaya. The sculpture stands just under seven feet and was a hit among the school groups and families that visited the Saint Louis Science center throughout the day.

The DNA celebrations continued with an overnight DNA themed camp-in at the science center, where nearly 60 campers and chaperons had the opportunity to build DNA key chains, extract DNA from fruit, and participate in DNA Disco.
